I just got a Betta today. I put him in an aquarium which is approximately 20 gallons (the reason I say "approx" is because the sand and ornaments decrease the space). Anyway, it has a cycled filter and a heater (set to 25'C)
But, I've read on the internet 20 gallons is too big for a Betta and will make it feel "uncomfortable" ?! Is this true?
Any other tips on keeping a Betta fish?
His only tank-mates are five Zebra Danios...
I have plenty of cold water fish experience... But I am lacking in the tropical department!!
Thanks for your help
